The average daily traffic from April 2014 to March 2015 was 1.4% higher than the average from April 2013 to March 2014. The trend shows a continuous modest recovery in traffic that dates back to April 2013. 1,7% SEP 1,8% OCT 1,8% NOV 1,8% DEC 1,6% JAN 1,5% FEB 1,4% The low-cost segment maintained its dominant position with a growth rate around 8% since the beginning of 2015 whereas the allcargo segment recovered from -1.1% in January to +1.5% in March. Charter was the weakest of the market segments and was down 8.8% on March last year and was followed by business aviation and traditional scheduled, both segments were down 0.9% and 0.2% respectively on March 2014. With circa 230 extra daily flights, UK was the main contributor to local traffic 1 and followed by Turkey and Spain each adding 140 and 120 daily flights respectively to the European network. Germany was back among the top contributors and added 70 daily followed by Italy and Greece, both countries adding each 70 flights per day. Portugal, Poland, Ireland, Belgium/Luxembourg and Romania were the other countries adding more than 25 flights per day to the network. At the other end of the scale, the 8-day strike at Norwegian Air Shuttle in March resulted in circa 110 fewer daily flights for Norway (vs. March 2014). The overall traffic decrease in Ukraine was 74% representing a fall of 28% (100 fewer daily flights) in the state s local traffic and a fall of 98% in its overflights (vs. March 2014). Traffic re-routing via neighbouring states resulted in overflight increases for Bulgaria (+48%), Romania (+25%), Turkey (+21%) and Hungary (+2) and overflight decreases for Moldova (-6) and Armenia (-3). The closure of the Libyan airspace shifted eastwards traffic flows between North West Europe-Southern Africa resulting in overflights increases for Greece (+15%) and decreases for Malta (-22%).

Six of the top 10 airports recorded positive traffic growth compared to March 2014. Overall, the largest traffic increases in March 2015 were at London/City, Athens, Istanbul/Sabiha Gokcen, London/Stansted, Dublin, London/Luton, Birmingham, Lisbon, and Warsaw airports. London/City traffic increased significantly mainly due to the start of Flybe operations. The largest traffic decreases were at Oslo/Gardermoen, Bergen/Flesland, Prague, Gran Canaria and Milano/Malpensa airports. Five of the top 10 aircraft operators had more traffic compared to March 2014. Overall, the operators with the highest traffic growth were Germanwings, CityFlyer Express, Wizz Air and Vueling. Lufthansa, Norwegian Air shuttle, Finnish Commuter Airlines, Transavia, Air Baltic and HOP recorded the highest traffic decrease compared to March 2014. The 8-day strike at Norwegian Air Shuttle influenced its traffic decrease. The transfer of certain Lufthansa flights to Germanwings accounted for some of the variation in traffic in these carriers. Pegasus continued to record an increase in flights compared to March 2014 following an increase in fleet size. NM Monthly Network Operations Report - Analysis - March 2015 3
The large traffic changes in the Italian ACCs are due to resectorisation in April/May and November 2014. Traffic avoiding the Ukraine airspace continues to increase traffic flows in Sofia and Bucharest ACCs, but with a significant traffic decline continuing in Chisinau and Yerevan ACCs. Skopje ACCs traffic increase continued in March following the re-opening of the Kosovo KFOR sector in April 2014 and an increase in traffic to Skopje airport. Increased traffic in Athens, Makedonia and Nicosia ACCs is due to traffic avoiding Libya and Syria. Malta ACC continues to be affected by the changes in Libyan airspace availability. Beograd, Budapest, Reykjavik, Cairo and Santa Maria ACCs experienced a significant increase in traffic. NM Monthly Network Operations Report - Analysis - March 2015 4

A similar trend can be observed for the last four months. Airport weather (39.3%) was the biggest contributor to ATFM delays in March, followed by airport capacity (15.9%) and enroute ATC capacity (15.6%). These are the top 20 delay generating locations for the reporting month with respect to total ATFM delays. Figures are the average daily delays in minutes for the individual locations. Weather (mainly strong wind, snow and low visibility) impacted airport operations, particularly at Amsterdam/Schiphol, London/Heathrow, Zurich, Oslo/Gardermoen airports. Nicosia ACC recorded high delays due to ATC staffing/capacity issues. Reduced capacity due to system upgrades and Israeli military activity also contributed to the delays. Istanbul/Ataturk and Istanbul/Sabiha Gokcen airports continue to experience delays due to aerodrome capacity issues. Amsterdam/Schiphol airport s implementation of VCS (trials and transition) produced delays. Brest, Reims, Paris, Lisbon and Maastricht ACCs generated delays due to en-route ATC capacity. Brest also generated delays linked training for ERATO implementation. NM Monthly Network Operations Report - Analysis - March 2015 5

6. ALL AIR TRANSPORT DELAYS (Source: CODA) This section presents the all air transport delay situation as seen from the airlines by using the data collected by Central Office for Delay Analysis (CODA) from the airlines. Data coverage is 65% of the commercial flights in the ECAC region for February 2015. ATFM delays reported by airlines may be lower than the NM calculated ATFM delays due to difference in methods: ATFM delays of NM are the (flight) planned delays ; the airlines report the actual experienced ATFM delay on departure. For instance, a flight with an ATFM delay may also have a handling delay absorbed within the ATFM delay. For the airline, a part of this delay is the ATFM delay and the rest is the handling delay. Based on airline data, the average departure delay per flight from All Causes was 9.4 min/flt. This was an increase of 26% in comparison to 7.4 min/flt in the same month in 2014. Within all air transport delays, en-route ATFM delays were 0.1 min/flt in February 2015. Primary delays counted for 57% (or 5.3 min/flt) of which 0.1 min/flt was attributed to en-route ATFM delays, with reactionary delays representing a smaller remaining share of 43% at (4.1 min/flt). Further analysis of airline data shows that the average en-route ATFM delay was 0.1 min/flt. This was the same as the NM reported average en-route ATFM delay of 0.1 min/flt. The percentage of flights subject to long ATFM restrictions (those exceeding 15 & 30 minutes) increased slightly with flights with restrictions exceeding 15 minutes at 1.5%. The percentage of flights delayed from allcauses also increased (those exceeding 15 minutes) increased by 3.4 percentage points to 15.1% and those (exceeding 30 minutes) also increased to 7.2%.

SIGNIFICANT EVENTS AND ISSUES PLANNED EVENTS ACCs During March, six ACCs carried out projects involving ATM system upgrades, all of which were categorised as special, planned events with potential impact on the network performance. The performance of the network was affected as follows: Madrid ACC The implementation and transition to SACTA CF 2 system: the project was in its post-transition phase until 05 March, and generated 385 minutes of delay (no capacity reductions previously estimated). This represented over 23% of all delays (1,613 minutes) for Madrid ACC during March. Zurich ACC The implementation of the Stripless CH system, Step 3: the project was completed on 10 March generating 4536 minutes of delay (previously estimated capacity reductions 10-2). This represented over 61% of all delays (7,396 minutes) for Zurich ACC during March. Brest ACC Performed training for the implementation of the ERATO Electronic Environment throughout March generating 6,044 minutes of delay (Medium network impact estimated). This represented over 23% of all delays (25,797 minutes) for Brest ACC during March. Bordeaux, Munich, and L viv ACCs performed training for the operational staff for the system upgrade projects (L viv started transition phase on 16 March). Bordeaux training was expected to have a medium network impact and no impact was expected for the other two - no delays were recorded for all three.
